Check Out This Cool Home-Made .700 Caliber “Dinosaur” Gun

” The cartridge, named the .700 WTF (“What The F…”) and is made by fire forming a .50 BMG brass case, trimming it to 3″ in length and then sizing it. The round is loaded with a 1132 grain paper patched .700 lead cast bullet.”

” The rifle, with just a 16.25″ barrel, can push the 1132 grain of lead up to 2300 fps. Thats 13,000 ft/lbs of energy, right up there with the .50 BMG and far exceeding the .700 Nitro Express. The cast lead bullet has enough energy to pass clean through a 1/4″ steel plate.”
